Uncomfortable with change in engine feel
Reviewed in the United States on December 11, 2018
I used this in my CX-5 for 7,000 miles. Prior to and since then, I use Mobile ONE. When the Castrol was used, I could feel an occasional stutter in the engine while idling. I likely wouldn't have noticed this if I had used it from the beginning, and it probably isn't really doing any damage. Based on my non-scientific analysis and non-mechanical opinion I prefer to use Mobile ONE at this point since the stuttering isn't present.
